ABSTRACT:
A change return control for a money handler in a vendor capable of a plurality of customer selectable transactions at different prices, the money handler having circuitry for identifying the denominations of money deposited in the vendor. The control includes circuitry for determining if a coin storage means in the money handler contains first and second predetermined amounts of change, and a vend control for permitting a vend. Logic circuitry determines the amount of credit accumulated as a result of each deposit of money in the vendor, compares the price of a selected transaction with the accumulated credit, and governs the vend control. A vend requiring more than the first predetermined amount of change is allowed only if an item of money of a denomination greater than the amount of change required has been deposited in the vendor. The logic circuitry is responsive to the deposit of an item of money of a first predetermined denomination in the vendor and to the difference between the accumulated credit and the price of the selected transaction being at least as large as the first predetermined denomination to prevent the vend. Display circuitry displays the maximum amount of change that can be returned.
